Member Function Documentation

◆ ata_pass_through()

bool sat::sat_device::ata_pass_through	(	const ata_cmd_in &	in,
		ata_cmd_out &	out
	)

overridevirtual

ATA pass through.

Return false on error. Must be implemented in derived class.

Implements ata_device.

Definition at line 259 of file scsiata.cpp.

◆ autodetect_open()

smart_device * sat::sat_device::autodetect_open ( )

overridevirtual

Open device with autodetection support.

May return another device for further access. In this case, the original pointer is no longer valid. Default implementation calls 'open()' and returns 'this'.

Reimplemented from smart_device.

Definition at line 522 of file scsiata.cpp.

◆ scsi_pass_through()

bool sat::sat_device::scsi_pass_through ( scsi_cmnd_io * iop )

overridevirtual

SCSI pass through.

Returns false on error.

Implements scsi_device.
